OANCHORING DEVICE. FOR TRACTORS.

SPECIFICATION forming part of Letters Patent No. 782,643, dated February 14, 1905.

Application filed July I6, 1904. Serial No. 216,885.

To all 1072,0711, it may concern:

,Be it known that I, ANDRE CASTELI'N, engineer, a citizen of the French Republic, residing at'Paris, France, have invented certain new and useful Improvements in Anchoring Devices for Tractors Used in Operating Agricultural Implements, of which the following is a specification.

This invention relates to new and useful im- IO provements in anchoring devicesfor tractors used in operating agricultural implements, and has for its object the construction of an anchoring device adapted to be secured to a tractor used for operating agricultural imple- 5 mentssuch as plows, mowers, reapers, and

the likewhich device will effectually prevent movement or overturning of the tractor when operating such implement.

In anchoring devices as heretofore constructed it has been found that when the tractor is set in operation to draw a plow across a field, for example, the horizontal pull upon the cable attached to the plow and the weight of the tractor have a tendency to lift or turn 5 the tractor on the fulcrum formed by the hearing of the anchor on the ground, and thus frustrate the very object of the device. My invention overcomes this difficulty and provides a means which will not only prevent the 3 tractor from turning on the free end of the anchoring device as a fulcrum, but also serves to lift the anchoring device from operative relation and secure it in such position while the tractor is being moved from place to place.

Other objects of my invention will hereinafter appear.

In describing my invention in detail reference is had to the accompanying drawings, in which I have set forth the preferred embodi- 4 ment of the invention; but it is to be understood. that I do not limit myself to the details of construction therein set forth, but changes,

variations, and modifications may be made therein as come'within the scope of the protection prayed- Referring to the drawings, Figure 1 is a diagrammatic view of a tractor adapted to 0perate an agricultural implement from its rear described in detail.

end and having my improved anchoring device attached to its forward end; Fig. 2 is a diagrammatic view of. the same tractor having my improved anchoring device secured to its rear end. Figs. 3 and 4 are a side elevation and plan view, respectively, showing a portion of a tractor equipped with my improved anchoring device at its forward end, the former showing the anchoring device in operative relation and the latter showing the anchoring device when raised out of operative relation.

Referring to Figs. 1, 3, and A, the reference character 1 denotes the tractor used for operating an agricultural implement from its rear end. This tractor may be of any known construction, such as the well-known traction-engine, and therefore will not be illustrated or 2 denotes a frame formed of side and'end members and provided at one end with anchors or spades adapted to enter the ground. Each of these anchors consists of an angle-iron suitably secured by bolts or rivets to the lower end member of the frame and so arranged that one member, 5, forms a spade to penetrate the ground, and the other member, 4, extending at an angle thereto, will bear upon the ground and limit the penetration of said member 5. One or more of these anchors may be employed, according to the width ,0f the frame 2. The frame 2 is arranged for connection with one end or other suitable part of a tractor and is adapted to extend at an angle thereto in the same direction as the cable connected to. the implement to be operated.

=In Figs. 3 and 4 of the drawings I have shown the frame 2 as provided at its upper end with eyes through which extend lugs or pins depending from the lower surface of the tractor-bed and extending transversely thereof. To each end of that end member of the frame 2 which carries the anchors or spadesis secured an eye or'other suitable device, to which is attached one end of a chain, rope, or other suitable device which has its other end suitably secured to the tractor at some distance from the point of attachment of the frame 2to the tractor. Ihave shown in Fig. 3 of the drawings a chain 6, having one end provided with a hook adapted to engage the eye on the frame 2 and having its other end secured to and adapted to be wound upon a drum or shaft 7, mounted upon the tractor. A ratchet-and-pawl mechanism serves to rotate the drum or shaft 7 and wind the chain 6 thereupon. Instead of the chain 6 a rope, cable, or other flexible device may be used.

In Fig. 2 I have shown a diagrammatic view of a tractor having my anchoring device attached to the rear end thereof. When so used, the anchoring-frame 2 is hingedly connected to the rear end of the upper surface of the tractor-bed, as at 3, and is provided with an upward extension 12. The chain or other device is connected to the free end of said extension and has its other end connected to and adapted to be wound upon a shaft or drum 7',

which is preferably mounted on the upper surface of the tractor-bed.

It will be evident that in the absence of the chain or other device 6 when the tractor is set in operation and the anchors 2 have penetrated the ground the pull exerted by the resultant force 10 of the horizontal component 8-(due to the tractive force on the cable drawing the implement toward the tractor) and the vertical component 9, (due to the weight of the tractor,) Fig. 1, being exerted within the angle formed by the lower surface of the bed of the tractor and the anchor-frame 2 would have a tendency to lift or turn-the tractor upon the fulcrum 11, formed by the lower end of said frame. This is effectually prevented by the chain or other device 6, which in combination with the bed of the tractor and the frame 2 forms a triangle the angles of which cannot be changed or distorted after once being set. Similarly when the anchoring-frame 2 is attached to the rear end of the tractor-bed, as shown in Fig. 2, the resultant force of the horizontal and vertical components 8 and 9, acting at the point 3, (the point of connection of the anchor-frame with the tractor-bed,) being exerted outside the angle formed by the anchor-frame 2' and the rear end of the tractor has a tendency to lift or turn the tractor on the fulcrum 11, formed .by the lower end of the anchor-frame, and

thereby move or overturn the tractor. Here the chain or other device connected at one end to the free end of the extension 12 of the anchor-frame 2' and at its other end to the upper surface of the tractor-bed prevents such movement or overturning. It will therefore be perceived that the chain or other device serves both to prevent the lifting or turning of the tractor upon the fulcrum formed by the anchoring-frame and also as a means for lifting said anchoring-frame from the ground when not in use or when it is desired to move the tractor from place to place.
